So, I was trying to install the sync client for Mega (http://mega.nz) on my Ubuntu 15.10 install. Yes, I know it's pre-release, but here is my question: When i install the .dep file, I get that

Errors were encountered while processing:
 megasync
dpkg: dependency problems prevent configuration of megasync:
 megasync depends on libcrypto++9; however:
  Package libcrypto++9 is not installed.

When I then try to install libcrypto++9, I get the following error:

E: Package 'libcrypto++9' has no installation candidate

It then tells me that libcrypto++9v5 replaces it, but installing that doesn't satisfy MegaSync.

A quick Google search reveals that the v5 means "compiled using gcc5". Alas, the library is still the same. Why the new name, and how can I install my .deb file?

For Ubuntu 15.10 (All Versions):

Add this repository to your /etc/apt/sources.list (check here for other versions):

deb https://mega.nz/linux/MEGAsync/xUbuntu_15.10/ ./

Get/Add the key:

wget -O - https://mega.nz/linux/MEGAsync/xUbuntu_15.10/Release.key | sudo apt-key add -

Update: sudo apt-get update

Install MEGASync:

sudo apt-get install megasync

For Nautilus plugin:

either download packages libcrypto++9 from here and install it using command :

sudo dpkg -i libcrypto++9_5.6.1-6+deb8u1build0.15.04.1_amd64.deb

or

it is in universal packages so add universal repository if not added and install using command 

sudo apt-get install libcrypto++9

i have tested this in ubuntu 14.04 so megasync also depending on libc-ares2 packages download it from here and install it using command 

sudo dpkg -i libc-ares2_1.10.0-2_amd64.deb

or

it is available in main Ubuntu repository so add if not added and install using command 

sudo apt-get install libc-ares2

then try to install megasync

sudo dpkg -i megasync-xUbuntu_15.04_amd64.deb

  • Sorry, I've been forced AFK. I have `universal` enabled. The problem only exists in ubuntu 15.10 because of the switch to gcc5 – bpou Sep 28 '15 at 13:23
  • @bpou did you get it fixed? I'm upgrading my 15.04 -> 15.10 and i'm having the same issue. It was there in 15.04 to, but i can't remember how i fixed it. – mote Oct 27 '15 at 09:46
  • I manually edited the dependencies of the deb file. HOWTO here: http://ubuntuforums.org/showthread.php?t=110458 – LinuxStudent Nov 27 '15 at 16:18

None of the solutions I found in the web worked so I tried the following:

I downloaded libcrypto++9 from here, and installed it as a .deb. http://archive.ubuntu.com/ubuntu/pool/universe/libc/libcrypto++/libcrypto++9_5.6.1-6_amd64.deb

The same for libc6 from: http://ftp.br.debian.org/debian/pool/main/g/glibc/libc6_2.31-4_amd64.deb

Then I downloaded libqt5gui5-gles_5.15.1+dfsg-2_amd64.deb from http://ftp.br.debian.org/debian/pool/main/q/qtbase-opensource-src-gles/libqt5gui5-gles_5.15.1+dfsg-2_amd64.deb

You should do it with any package that is missing in your own configuration. I recomend this website to find them: https://pkgs.org/

  • This answer can break a system since it not only advises installing software from .deb files, but the answer also suggests installing packages from other distributions. Additionally, pkgs.org is not an official mirror or source for Ubuntu software. When there are official sources like https://packages.ubuntu.com, referring users to unofficial software sources poses an unnecessary risk. This answer also lacks [formatting](https://askubuntu.com/help/formatting), which is needed so the names of packages can be distinguished from the surrounding text. – Nmath Nov 08 '20 at 21:26
